Kisspeptin-10 for testosterone: outcomes in published studies
OutcomeResultStudy typeSource
LH, FSH and testosterone (acute)Acute kisspeptin-10 infusions raised LH, FSH and testosterone dose-dependently versus vehicle (P < .0001).Human RCTn = 15European journal of endocrinology 2026, PMID 42549827
Continuous 5-day infusionAfter 5 days of continuous infusion testosterone stayed elevated but gonadotropins matched vehicle.Human RCTn = 15European journal of endocrinology 2026, PMID 42549827
Intermittent 12-day dosingDaily 8-hour infusions over 12 days sustained gonadotropin increases.Human RCTn = 15European journal of endocrinology 2026, PMID 42549827
Testosterone during infusionAt 4 ug/kg/h for 22.5 h, LH rose from 5.4 to 20.8 IU/liter and testosterone from 16.6 to 24.0 nmol/liter.Human controlled trialThe Journal of clinical endocrinology and metabolism 2011, PMID 21632807
Sexual dimorphism of responseKisspeptin-10 raised gonadotropins in men and in preovulatory women but not in follicular-phase women.Human uncontrolled trialThe Journal of clinical endocrinology and metabolism 2011, PMID 21976724

How strong is it?

Strongest evidence:Human RCT evidence, 4 of 4European journal of endocrinology 2026, PMID 42549827

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.
